STL Viewer

STL or STereoLithography is a file format created to support prototype design using solid free-form fabrication technology.
The format is relatively well known and is used with a multitude of CAD applications. Such a file only contains the surface geometry of a 3D object. Colors or textures are not available as it is custom for most objects exported from a 3D CAD application.
STL Viewer is a lightweight tool that provides a very simple means of opening and exploring these files. It displays a minimalistic interface which allows you to only focus on the object that is presented in front of you.
Since STL files contain little information, the objects can be freely moved inside the application without any loading time or motion delay. You can rotate the 3D object any which way you want using your mouse. The object can also be moved vertically or horizontally, as well as zoomed in or out. It’s exactly what an efficient viewer should be able to do.
In case you need to, STL Viewer offers you the option to set a scaling factor which you can type in. Moreover, the application is capable of extracting some information about the loaded object. It displays the number of existing facets (triangles), as well as the total surface area of the object.
Because of its small size and the fact that STL Viewer does not depend on other applications for it to be able do the job, it’s a very practical tool to have around when you simply need to share and view a design. You can even email the application along with the file itself if the recipient doesn't have the means to open it.
In closing, STL Viewer is indeed a handy application which can certainly help you out when it comes to viewing an STL file.
